The lens is remarkably clean for its age, with minimal dust and no haze. The aperture, helicoid, and infinity lock all function without issue. The copper mirror also has no noticeable scratches and is in very good condition. Included items: K&F ML ring (will be shipped attached) Front and rear caps (aftermarket, the rear cap is for Leica M) Please note that I have selected the Nikon F mount due to Mercari's system, but this lens is a Leica L39 mount. Focal length: 19-70mm Maximum aperture: 1.5-2 Other features: Lens hood, front lens cap, rear lens cap, vintage lens
